Improvement in pump-pistons



PATE *E AMOS H. FOE, OF STRATHROY, CANADA.

IMPROVEMENT IN PUMP-PISTONSV.

Specification forming part of Letters Patent No. 120,054, dated October17, 1871.

To all whom t may concern:

Be it known that I, AMOs H. FOE, of Strathroy, in the county ofMiddlesex and Province of Ontario, Canada, have invented a new anduseful Improvement in Pump-Valves; and I do declare that the followingis atrue and accurate description thereof, reference being had to theaccornpanying drawing and to the letters of reference marked thereon,and being a part of this speciication, in which- Figure lis aperspective of my valve or sucker,77 attacked to the rod. Fig. 2 is asection of the saine, showing the internal construction in perspectivewith the collar removed.

Like letters refer to like parts in each figure.

The nature of this invention relates to an improved construction ofpump-valves or suckers, which will combine cheapness of constructionwith efficiency and durability. It consists of forming the valve-seatframe of an upper and under portion made of any suitable metal, with awasher between the same made of leather, and in the combination of saidparts with a valve 'and collar and rod, as more fully hereinafterdescribed. p

In the accompanying drawing, A represents the lower section cast with ashoulder, a, which latter is designed to fit the bore of the pump-log,and upon it the lower edge of the collar rests.

B is the upper section provided with a series of holes, b, through it,and between it and the upper section A is placed the leather section C.The valve D rests upon the upper section, and

covers the aperture E, which is of the same dimensions through each ofthe sections. The valve is secured by suitable nails driven through theleather packing', and through the holes b and leather section O, andclinched on the under side thereof by impact with the top of the lowersection A. F is the rod7 to the lower end of which the seat-frame issecured by the straps G, the lower ends of which pass through sections AB O, and hold them rigidly together by means of the nuts d, which engagewith suitable threads on the lower ends of the straps. The collar H,which is of leather or other suitable material, is nailed to place, asshown, the nails being driven through it into the latter section O.

It will readily be perceived that this sucker or valve-seat frame willbe much more durable than those made of wood in the ordinary manner.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The valve-seat frame or sucker of the three sections A B C, in such amanner as will admit of nailing on the valve and collar, substantiallyas herein set forth.

2. The arrangement of said sections A B C with the valve D, rod F, andstraps G, and collar H, substantially as set forth.

AMOS H. FOE.
